CARL WINKLER; or BERNE, SWITZERLAND. MOLD non cns'r-inefsrnnnorxrnPLATES.

Application filed March 21, 1925 Serial No. 17,372.-

To all whom it may concern:

Be it known that I, CARL WINKLER, a citizen of the Swiss Republic,residing at Berne, in the Swiss Republic, have invented new and usefulImprovements in Molds for Cast.- ing Stereotype Plates, of which thefollowing is a specification.

The invention relates to a mold for cast previous to casting a plate, itcan be tested whether the matrix has the right position 'in the mold.

In the drawing illustrating the invention by way of example.

Fig. l is a perspective view of the mold in the casting position, and IV Fig. 2 a similar view of the mold with'the matrix clamp, side and footbars partly raised.

The matrix clamp (1!. turns about the axis b and holds one edge of thematrix. Tothe side bars d the matrix clamp d is connected by pinsfastened to saidbars,-which pins project into the guides e on the matrixclamp, so that by raising the inner edge of this clamp from the positionin Fig. 1 into that shown 'in Fig. 2, which is done by pressing down thehandle 7, the bars d are also raised. At the same time the'footbar g isturned up a little by the side bars. Consequently, the matrix 0 is 'freeunder the side bars d and the foot bar 9, so that it can take part inthe small movement of the matrix clamp. By raising and lowering theclamp it can therefore be ascertained whether the matrix is properlyseated in the mold.

What I claim and desire to secure by LettersPatent of the United Statesis:

A mold for casting stereotype plates comprising in combination a matrixclamp for holding one edge of the matrix, side bars connected to saidclamp, a foot bar connected to said side bars, and a handle on saidmatrix clamp adaptedto tilt said clamp side bars and foot bar,substantially as set forth.

In testimony. whereof I have-signed my name tothis specification inthepresence of two subscribing witnesses.
